Abstract
A method for presenting a face in a video call includes: obtaining a key feature point of a facial expression of a user based on a face image of the user; driving a three-dimensional (3D) head image of the user by using the key feature point of the facial expression of the user, to obtain a target 3D avatar of the user, where the target 3D avatar of the user has an expression of the user; rotating the target 3D avatar based on a preset presentation angle, to obtain a target 3D avatar at the preset presentation angle; and transmitting the target 3D avatar at the preset presentation angle to a peer video call device. A user can see a 3D avatar that is of a user and that is at a preset presentation angle in real time.
